Displacement magnification corrugated web damper

Abstract

The invention relates to a displacement magnification corrugated web damper, which comprises an upper connecting plate with a rack, a gear, a duplicate gear, a center shaft, a lower connecting plate with a rack, a frame, a sliding groove cross beam, a fixing bottom beam and a corrugated web damper body. The displacement magnification corrugated web damper has the characteristics that the structuredesign is simple, selected material and machining costs are low, overall mounting and construction are convenient and rapid, and firmness and durability are achieved; and when the interlayer deformation speed and displacement of a structure are relatively small, through rotation of the duplicate gear, deformation can be quickly enlarged effectively, thus the relative displacement of the damper becomes large, damping of the structure is increased, the energy-dissipating earthquake reduction capacity of the damper is given into full play, thus the overall energy-dissipating capacity of the structure is improved, and damage caused by the earthquake response to the building structure is effectively reduced.

Description

technical field [0001] The invention relates to a displacement amplification corrugated web damper. Background technique [0002] Under the action of a large earthquake, the traditional structure mainly relies on some components to absorb a large amount of seismic energy, so that the entire structure enters an elastic-plastic state or even yields and fails, which leads to the entire structure being irreparable or even directly collapsed after the earthquake. Structural energy dissipation and shock absorption technology is a new earthquake-resistant and disaster-prevention technology. By setting shock-absorbing components and energy dissipators in some parts of the structure with large deformations, such as viscous dampers, mild steel dampers, and friction dampers Wait. When encountering earthquake loads and wind loads, these energy-dissipating components can quickly enter the energy-dissipating state, consume the energy transmitted to the structure by the earthquake through...

AI Technical Summary

Problems solved by technology

[0003] At present, in the field of structural energy dissipation and shock absorption technology, the biggest problem with dampers is that they cannot fully exert their energy dissipation and shock absorption capabilities.

When the damper is working, its speed and displacement are the same as the speed and displacement of the structural connection point. When the speed and displacement of the structural connection point are relatively small, the elastic-plastic deformation of the damper is small, so that it cannot fully exert its energy dissipation and shock absorption.
